The Hardy Boys/Nancy Drew Mysteries (re-titled The Hardy Boys for season three) is an American television mystery series based on the Hardy Boys and Nancy Drew juvenile novels. The series, which ran from January 30, 1977, to January 14, 1979, was produced by Glen A. Larson from Universal Television for ABC. Parker Stevenson and Shaun Cassidy starred as amateur detective brothers Frank and Joe Hardy, respectively, while Pamela Sue Martin (later Janet Louise Johnson) starred as amateur sleuth Nancy Drew. The Hardy Boys/Nancy Drew Mysteries was unusual in that it often dealt with the characters individually; the series alternated between episodes that featured the Hardys and episodes featuring Drew in its first season. As the series progressed, the two storylines crossed over, and the Nancy Drew character was drastically reduced, and then dropped, in favor of the Hardys. Synopsis Season one (1977) The titular "Hardy Boys", Frank and Joe, are brothers and amateur detectives from the fictional city of Bayport, Massachusetts. The boys live with their famous father, Fenton Hardy, a private detective who spent two decades with the New York Police Department, and his sister, the boys' spinster aunt Gertrude. The boys are frequently assisted by their friend, Callie Shaw, who does part-time work for their father. Nancy Drew is an amateur sleuth — although she prefers the term "part time investigator" — and daughter of defense attorney Carson Drew. The two live in the fictional town of River Heights, New Jersey. Nancy solves mysteries with her best friend, George Fayne, and her father's paralegal, Ned Nickerson, with whom she shares an ambiguous romantic connection. The Hardy boys' friend Chet Morton only had a brief role in the series. The Callie Shaw character was changed drastically from the books, where she is Frank's girlfriend. For Nancy Drew, the Ned Nickerson character was also changed; in the books, he was Nancy's boyfriend, who attended college, and was the football quarterback. Season two (1977–78) With the second season came some serious story and character changes. For the Hardy Boys episodes, all supporting characters except for Fenton Hardy were dropped, and unmentioned. For the Nancy Drew episodes, Ned Nickerson was erased at first, but then later came back for one episode as the Assistant District attorney from Boston. Played by a different actor, Ned was re-introduced to Nancy Drew as if they had not previously known each other. Bess Marvin is also
